The YOU MIGHT NEED SOMEBODY hitmaker understands the pressure in showbiz circles to indulge in illegal stimulants, particularly as she previously battled a damaging cocaine dependency herself.
But the now sober 26-year-old believes motherhood is sacred, and if she hadn't ditched drugs, she could never have been a good parent to her two-year-old son MEKHTI.
She says, "Kate is a role model to lots of young girls who want to emulate everything she does. But more importantly, she's a mum. If you're doing a lot of cocaine like I was, you feel jittery and paranoid. I wouldn't be able to run around and play with my son if I was coming down from a drugs binge.
"I personally don't understand how Kate has a child and can still be living that lifestyle. It's very selfish.
"I do feel sympathy for Kate. In the entertainment industry, people party a lot. The pressure is immense."
Moss is reportedly seeking help at the Meadows Clinic in Arizona.
